[0002] At present, the common construction technology used in coal mine semi-coal rock and rock tunnels is to use comprehensive tunneling machines for excavation. In order to control the high concentration of dust generated by the tunneling machine cutting the coal rock, a long-pressure short-extraction ventilation and dust removal system is often used. The long-pressure short-extraction ventilation and dust removal system uses a pressure-type local ventilator to deliver fresh air to the working face, and dust removal fans and dust extraction ducts are arranged on the working face.
